Application filed June 11, 1913. Serial No. 773,012.

My invention has relation to permutation locksand 15 designed primarily for use on automobiles and like vehicles tojprevent the sons, and the object thereof is to provide a simple and efficient lock for that purpose.

In the present instance, I have shown my device asapplied to the clutch lever of an automobile and will describe it as so applied, but it will be understood that I do not limit myself to such application. I accomplish this object by the device described herein and illustrated in the accompanying draw ings forming a part hereof in which! Figure 1 is a diagrammatic View of my device as applied to an automobile. Fig. 2 is a front elevation of Fig. 1. Figl 3 is a rear elevation of the lock with the cover removed. Fig.4 is a section on the line 4-4 Fig. 3. Fig. 5 is a central vertical section Fig. 6 is a top plan partly broken away and parts removed for clean ness of illustration. Figs. 7 and Sare demember and its parts.

In the drawings 10 is the lock case which may be of any suitable size or shape, preferably rectangular, in one end of which are dove-tailed slots. 11 and 12longitudinally thereof. Slide blocks 13 and 14 are slidably mountedi nslots 11 and 12.

On the inner surface of the casing 10 at the end opposite slots 11 and 12 at adis tance from the front of the casing is rigidly having a groove 16 therein. vA similar block 18 therein. These blocks to side of the casing.

slida'bly mounted slide horizon- The side rails of frame 19 have 20 and 21 therein. A rectangular. mounted between the and has a groove extend fronrside rectangular frame 19 1s tally.

have invented new and useful Improvements in COIIIbHIZLUOH LOCkS, i of which the following is the SPGClfiCtttlOIlg 17 is mounted in the casing adjacent the other end thereof is adjustable horizon-. A rectangular locking block 26 is mounted in frame 23 in grooves in the side rails thereof and is adjustable vertically by screws 27 and 28. Block 26 has a port or opening 29 centrally thereof. g

A locking bar 30, having one of its ends 30 turned outwardly to project away from block 26, is pivotally mounted near said end 30 upon said block parallel with the face thereof at one side of opening 29 and has its longer leg, adapted to project over said openng and obstruct the same whcnthe device 18 in a locked position. A coil spring 30" havlng one end'secured to block26 and the other end secured to bar 30 between the pivot and timeout-turned end 30 serves to retain said bar in its locked position. Figs. 3and 7.) supported "11 a bracket 30 secured upon block 26. A flat spring 31 is also mounted (See on block 26 at an angle to bar 30 and is adapted to have one end extending across opening 29 and to retain bar 30 in an inoperative position. Secured toone side of the top rail of frame 22 and extending upwardlytherefrom is an inverted Tshaped guide bar gulde pin 34 extends through slot 33 and is 32 having a slot 33 therein. A

securedin block 17 An elevating member '35 having a slot 36 angularly disposed therein 1s secured to slide block 14 by screws or other means. A pin37 extends through end of bar32, so that when the block 14 is moved in elther direction guidepin 37 traveling in slot 36 willraise or lower frame A bracket 38 is secured to the undersideof block 13 to the end of which ispiv- "otally mounted a link 39. The other endof link 39 is pivotally secured to the upper end The other end of bar 30 is a slot 36 and is rigidly secured to the upper I of adjusting bar 40, the other end of which t is pivotally mounted on the side of block 15. Adjusting bar 40 has a slot 41 cut therein near the center thereof in which is received a pin 42. and is rigidly secured in oneside of frame 19 so that when block 13 is movedin either direct-ion bar 40 will, by means of pin 42, cause frame 19 to move horizontally. A re Pin 42 extends through slot 41 I leasing bar 43 is pivotally mounted between i 7 the sides of casing 10 adjacent thereof and a little below the center thereof. This bar is provided with a slot 44 longitudinally thereof and permits the adjustment of releasing trip 45 by means of ball the rear side a 45 to change the combination when desired as hereafter explained. Bar 43 has secured thereon at one end thereof an outwardly eX- tending lug or arm. 46 to which is pivotally secured the lower end of a releasing rod 47 which rod extends upwardly and passes through bearings 48 and 49 secured to one side of casing 10 and projects through the top of the casing. Suitable connections will be provided from the outer end of thisrodto the desired place of operation. 7

. A locking bolt 50 is slidably mounted in guide blocks 51 and 52 secured to casing 10 and the outer U-shaped end projects through a slot 53 therein when the device is in a locked position. The inner end of bolt 50 is provided centrally thereof with a studor pin 54 which is adapted to enter opening 29 in block 26 when the same is brought into register therewith. An unlocking rod 55 is mounted in bearing 56 in the front of casing 10 and has the upper end extending through. the top of the casing and is then bent to form a crank 57., The other end of rod 55 has a similar crank .58 thereon at a right angle to crank 57 the end of which is received in a slot 59 in bolt 50 so that when rod 55 is rotated by means of crank 57, crank 58 will move bolt 50 backward or forward to lock or unlock the device. Secured to rod 55 near the lower side of the top of casing 10 and preferably integral therewith is an arm 60 which is oppositely disposed from crank 57. Arm 60 is connected by a link 61 to one end of a rocking lever 62 pivotally mounted in a bearing 63 secured to the side of casing 10 near the top thereof. The other end of rocking lever 62 extends rearwardly and terminates in a hook 64 which hook is adapted to be received in the hooked end of a bracket 65 secured to the cover 66. L-shaped brackets 67 are also secured to cover 66 at the lower corners thereof and have slots 68 in the projecting legs thereof which are hooked over screws or studs 69 secured to the sides of the casing to secure the lower end of the cover in position. A stop block 7 O is secured to the cover at a point opposite bracket 65.

hen used on an automobile, the casing of my device will be attached to the floor of the car on the underside thereof or other convenient place so that the starting clutch lever 71 will pass alongside of the casing as shown in Figs. 1 and 2. This lever will be provided with slots or grooves 72 and 7 3 in the edges thereof which are adapted to be straddled by the U-shaped end of thelocking bolt and is prevented thereby from being moved longitudinally.

Blocks 13 and ,14 will be connected by rods 74 and 75 with operating handles or levers 76 and 77 which are pivotally mount ed on a semi-circular indicator plate 78 secured to the dashboard 79. This plate will vertical plane.

have marked on the circular edge thereof a series of notches (not shown) which will be numbered. Levers 76 and 77 will each have a notch (not shown) on the upper surface thereof which will be adapted to register with the notches in the indicator plate.

In the operation of my lock with the device in a locked position, should it be de sired to unlock the same the lever 76 will first be moved upwardly or downwardly as required by the combination then in effect. This will cause block 14 to be moved in a similar direction carrying elevating member 35 with it and by means of pin 37 traveling in slot 36 will elevate or lower frame 22 to bring the outwardly projecting end ;30- of bar 30 to a'plane just below the plane of the end of trip 45. Lever 77 will next be operated in like manner to lever 76. This will cause block 13 to be moved in the same manner as block 14. Block 13 will carry bracket 38 with it and by means of link 39 will rock adjusting bar 40 on its pivot and pin 42 traveling in slot 41 of said adjusting. bar will move frame 20 to a position so that the end 30 of bar 30 will be directly under the end of trip 45. Pressure will then be applied to the top of releasing bar 47 to- .move the same downwardly which will, by

means of lug or arm 46 cause bar 43 to be rocked thereby causing the end of trip 45 to strike and depress the endv 30 of bar 30. This causes bar 30 to be rocked on its pivot and elevate the other end thereof which uncovers opening 29. As soon as the end of bar 30 is sufficiently elevated spring 31 will snap under the elevated end. and prevent said end from returning to its normal position. Lever 76 will then be operated as before described to raise orlower frame 22 the desired amount to bring the opening in block 26 into register in a horizontal plane with stud 54. Lever 77 will then be operated as before described tomove frame 20 horizontally to bring the opening in the block 26 into register with stud 54 in a Unlocking rod 55 is then rotated by means of crank 57 which will cause crank 58 traveling in slot 59 to withdraw locking bolt 50 from contact with the clutch lever of the machine. bolt 50 is moved inwardly pin 54 will enter and pass through the opening in block 26 and will engage and push the end of spring 31 from under the end of bar 30 and allow said. bar to drop a short distance and rest upon said pin. Bar 30 will only drop a sullicient distance to prevent spring 31 mov- As locking ing under the end thereof "when the pin 54 V is withdrawn from the opening .inblock 26. When the lock is again locked and the locking bolt is moved to project out of the opening 53 in casing 10 pin 54 Will be withdrawn from the opening in block 26 which allows bar 30 to be returned to its normal position by spring 30 to again obstruct said opening and prevent the device being unlocked. When it is desired to change the combination bolt 15 is loosened and trip 15 is then free to be moved in either direction the desired distance when it is again tightened. Block 26 is moved in either direction vertically in frame 23 by means of screws 27 and 28. Frame 23 is moved in either direction in frame 22 by means of screws 24 and 25. Adjusting the positions of frame 23 and block 26 and trip 4L5 requires that blocks 13 and 14: be moved a greater or less distance in either direction and changes the combination of the lock.
